Open SpeedShop Now Available to Linux Developers
At SC|05, Demonstrations and Technical Sessions Shine Spotlight

on Popular Analysis Tool for HPC Open-Source Applications

SEATTLE, SC|05, Nov. 15 /PRNewswire-FirstCall/ -- Culminating a year of
joint development, the U.S. Department of Energy's (DOE) National Nuclear
Security Administration (NNSA) and Silicon Graphics (OTC Bulletin Board: SGID)
today announced that an open-source version of the SGI(R) SpeedShop(TM)
performance analysis tool is now available to developers.
Open|SpeedShop(TM), an open-source, multi-platform Linux(R) tool, helps
developers and end users analyze the performance of applications running on
single-node to large-scale IA32, IA64, EM64T and AMD64 platforms. The new
open-source tool is the result of a cooperative government/industry effort to
make more sophisticated open-source performance tools available to government
laboratories, universities and other researchers.
At the SC|05 Conference Nov. 12-18 in Seattle, Linux application
developers can attend a Birds-of-a-Feather session and ongoing demonstrations
of Open|SpeedShop.
-- Birds-of-a-Feather session: 12:15 to 1:15 p.m. Wednesday, Nov. 16, in
Room 615-616 of the Washington State Convention and Trade Center.
Jim Galarowicz from SGI and Martin Schulz from Lawrence Livermore
National Laboratory will discuss the current status of Open|SpeedShop
and the opportunities it presents to high-performance computing (HPC)
application developers and users.
-- Live demonstrations of Open|SpeedShop: Ongoing in the SGI Booth
(No. 602) and the NNSA Advanced Simulation and Computing (ASC) Tri-Labs
Booth (No. 402).
Developed by SGI in collaboration with Lawrence Livermore National
Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories,
Open|SpeedShop utilizes dynamic instrumentation technology developed at the
University of Wisconsin and University of Maryland.
The tool's base functionality includes program counter sampling, exclusive
and inclusive user time, CPU hardware performance counter, MPI event tracing,
I/O call tracing, and floating-point exception experiments. Designed to be
modular and extensible, Open|SpeedShop supports several levels of plug-ins
that allow users to add their own performance experiments. The tool's
infrastructure and base components are being released open source under GPL
and LGPL.
Key features of the powerful open-source tool include:
-- Three modes of operation: batch, interactive command line interface,
and graphical user interface
-- Multi-platform single system image, traditional cluster, and SGI super
cluster support
-- Support for large numbers of processes, threads, and ranks
